Are you on the Atkins diet or WW diet?

I am a nursing student writing a research paper for our nutrition cl. I have part of the diet section, to research. I am wondering if anyone has tried the Atkins/Low Carb diet, and if so what does a normal day consist for you as far as meals/snacks/exercise and some things that can be substituted incase you want to switch up a meal or a snack for a few days. I also need insight onto Weight Watchers with the same information as far as a normal day of meals, exercise, etc. Any other diet info that you may suggest that has been helpful is welcomed. I am working in a group and if I can't use the info, I'm sure someone else could benefit from it. Also if anyone has any helpful website links for Atkins & WW feel free to p them along. Thanks for any response!
